Hi all! Im currently using Manuel Bastioni for some character creation. Does anyone know how to export a finalized anime character with all materials including pupils into Unreal Engine 4 v4.18? Every time I do, the materials transfer over for skin and hair etc, but the eyes are just one whole material meaning they are solid white.![alt text][1]. The pupils seem to vanish?

Hi all,
I set up a system that takes FPS into account when measuring time, so 10 fps lads don't get an advantage over 600 fps lads. Now, I need to check if it works properly so I need to have a timer that starts counting after a certain function, and stops counting after a certain function then gives me the time in seconds.
The two functions are Setters, they are to set the enum state of a mechanical gate in the game:They have a height from which they are open, they move and after a height they are closed. They player has to enter just the right time, and as I gave heights, and use the Tick event to move the gates, needless to say that the FPS plays a huge role in the game.
So, these gates have a couple of states, but I care about two now: "CanEnter" and "TooLate". All the game logic is set, I just need to start a timer right after the state is changed to "CanEnter" and I need to stop it, and display the time right after the state is "TooLate". I saw timers on the net that count backwards. I need one to count forward and tell me the time.

Dear All,
I wish to know if it is possible to use Blueprints in Widgets as well?
Like, in the scene I use actor Blueprints that have their variables, functions and so on.
Now I'm converting my prototype into a final game logic and I use widgets instead of the original 3D ugly meshes I quickly made to set things up.
One of my objects get coloured in respect to its state (using an enum) and I did this with BP of course (as I said). But inside my widgets I don't seem to figure out if I can do that.

I created a blank game and already completed the game logic but I wish to change the project settings, namely:
Right now I can fly around in the game after hitting the play button. I wish to turn that off, but I find no blueprint that would be responsible for the movement.
The game is 3D now. I want to have a 2D game, without camera movement.and without any lighting, post processing or any fancy rendering (to get it run the fastest possible). I have the pre-rendered images that will build up the level.
Also I need the camera to be orthographic instead of perspective.

Hi all,
I've been following [this tutorial][1], updating the outdated parts as I go along and deleting the parts I don't think I need. This is a simplified version of my header file:
#pragma once
#include "GameFramework/Actor.h"
#include "MyActor.generated.h"
UCLASS()
class MYPROJECT4_API AMyActor : public AActor
{

UFUNCTION()
void OnOverlap(AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult);
UFUNCTION()
void OnEndOverlap(AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex);
public:
AMyActor();
virtual void BeginPlay() override;
virtual void Tick(float DeltaSeconds) override;
float RunningTime;
virtual void NotifyHit(UPrimitiveComponent* MyComp, AActor* Other, UPrimitiveComponent* OtherComp, bool BSelfMoved, FVector HitLocation, FVector HitNormal, FVector NormalImpulse, const FHitResult& Hit) override;
};
and a simplified version of my cpp
#include "MyProject4.h"
#include "MyActor.h"
AMyActor::AMyActor(const class FObjectInitializer& ObjectInitializer)
: Super(ObjectInitializer)
{
PrimaryActorTick.bCanEverTick = true;
CollisionComponent = ObjectInitializer.CreateDefaultSubobject<USphereComponent>(this, TEXT("SphereComp"));
CollisionComponent->InitSphereRadius(50.f);
OnActorBeginOverlap.AddDynamic(this, &AMyActor::OnOverlap);
OnActorEndOverlap.AddDynamic(this, &AMyActor::OnEndOverlap);
RootComponent = CollisionComponent;
}
void AMyActor::BeginPlay()
{
Super::BeginPlay();
}
// Called every frame
void AMyActor::Tick(float DeltaTime)
{
Super::Tick(DeltaTime);
//Define new atom position
FVector NewLocation = GetActorLocation();
SetActorLocation(GetActorLocation() + MyVelocity * DeltaTime, true);
}
void AMyActor::OnOverlap(AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
if (OtherActor != this)
{
GEngine->AddOnScreenDebugMessage(-1, 5.0, FColor::Green, ("Do the thing"));
}
void AMyActor::OnEndOverlap(AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)
{
GEngine->AddOnScreenDebugMessage(-1, 5.0, FColor::Green, ("Ok, don't do the thing"));
}
void AMyActor::NotifyHit(UPrimitiveComponent* MyComp, AActor* Other, UPrimitiveComponent* OtherComp, bool bSelfMoved, FVector HitLocation, FVector HitNormal, FVector NormalImpulse, const FHitResult& Hit)

FVector ReflectedVelocity = (-2 * FVector::DotProduct(MyVelocity, HitNormal) * HitNormal + MyVelocity);
MyVelocity = ReflectedVelocity;
ReflectedVelocity.Normalize();
}
This keeps giving me the following pesky error for OnOverlap and OnEndOverlap
Error C2664 'void TBaseDynamicMulticastDelegate<FWeakObjectPtr,void,AActor *>::__Internal_AddDynamic<AMyActor>(UserClass *,void (__cdecl AMyActor::* )(AActor *),FName)': cannot convert argument 2 from 'void (__cdecl AMyActor::* )(AActor *,UPrimitiveComponent *,int32,bool,const FHitResult &)' to 'void (__cdecl AMyActor::* )(AActor *)' MyProject4
(if you find other errors, this is a result of my hasty editing job to try and make my code shorter for this post). Does anyone know where I'm going wrong?
Thanks in advance!

Hi I have followed the tutorial on Creating a shared camera for multiplayer games, trying to create the camera similar to the way WWE's or Def jam fight for Ny's camera would be and still can't seem to get it all working. The camera and camera arm is all in the right position and the blueprint is the same of the tutorial, although the camera still isn't following the distance between X and Y (X and Y would represent the characters in the seen), Also when I press play, the camera isn't in the original position of where I placed it but instead is underneath the ground.!
![alt text][1]
In this pic the camera is zoomed into the wrong position (underneath the ground) after pressing PLAY.
[alt text][2]
![alt text][3]
This pic shows the Camera blueprint and that the player controls need to know to use the camera, and also get the camera to find the characters in the level.
![alt text][4]
This pic shows the camera blue print and basically works out the distance between the characters and when to zoom in or out depending on if the characters have moved closer or further away from each other.
